PADLOCK.

Specification of Letters Patent.

Patented Mar. 18,1913.

To all whom t may concern Be it known that I, FRANK SOLEY, a citizen ofthe United States, residing in-Philadelphia, Pennsylvania, have inventedcertain Improvements in Padlocks, of which the following is aspecification.

My invention relates to certain improvements in padlocks of the type inwhich a movable stump is used, which is arranged to aline with the slotsin the tumblers.

In the previous construction of locks the stumps were carried by a leverpivoted on the same post as the tumblers and in this type of lock in theevent of a wrong key being inserted therein the tumblers were liable toforce the stump out of alinement, thus destroying the usefulness of thelock. By my present invention, however, the stump is mounted on anindependent sliding plate supported by the casing so as to insure itsresisting any pressure of the tumblers to force it out of alinement, thestump being actuated by a pivoted lever controlled by the key.

In the accompanying drawings z-Figure 1, is an enlarged side view of apadlock illustrating my improvement; Fig. 2, is a sectional plan view onthe line 0 0, Fig. 1; Fig. 3, is a sectional plan view on the line --b,Fig. 2; Fig. 4, is a perspective View of the stump carrier; Fig. 5, is aperspective view of the lever for actuating thestump carrier; Fig. 6, isa perspective view of the bolt; Fig. 7, is a perspective view of one ofthe tum-blers; and Fig. 8, is a perspective view of the locking dogwhich engages the shackle.

Referring to the drawings, 1 is..the rear..

casing of the lock and 2 is the front casing secured together by rivetsin the ordinary manner.

3 is the shackle pivoted at 4 and having a nose with a single notch 5therein.

6 is the key post; the front section of the casing having a slot throughwhich the key is passed.

7 is the locking dog mounted on a post and having a notched end 9forming a hook 10 which enters the notch 5 in the end of the shackle 3.At the heel end of the shackle is a projection 11 which travels in closecontact with the rear surface 12 of the locking dog; holding it in itsopen position. When the lock is closed, as in Fig. l, the end of the dogprevents the movement of the `.shackle so that the shackle is held atthe geel, as well as at the nose, by the locking 13 is a spring mountedon the post 8 8 and bearing against the projection on the heel of theshackle and against 'the locking dog, acting as a spring to open theshackle, as well as to throw the dog.

14 is a slide carrying the stump 15, Fig. 4. This sliding carrier restsdirectly against the straight wall of the casing and is held therein bya post 16 and limited in its downward movement by a post 17. It isprevented from moving forward away from the surface of the casing at thelower end by the lever 18, Fig. 5, which is pivoted at 19, Fig. 3, to apost on a casing. This lever has a -projecting portion 20, which restsbetween the stump 15 and a lug 21 on the slide 14, so that upon themovement of this lever 18 the stump carrier will be positively moved ineither direction. A spring 22 is secured to the heel of the lever 18 andrests against the projection onv the casing, tending to normally holdthe' stump carrier against the stop 17 on the casing. The under side ofthe lever 18 is so formed that when the key is turned on its post 6, itwill lift the lever 18 and the stump 15 the distance required.

Mounted in front of the lever 18 is a sliding bolt 23 carrying tumblers30. The bolt and the tumblers are notched at the ends to receive thestump 15. There may be asmany notches as desired and these notches maybe located at any point at the end of the bolt and tumblers. In thepresent instance the lock is designed as a master key..lock and thereare two notches in each element.

The sliding bolt is shaped to be actuated by a key and is guided byprojections on the casing of the lock so as to have a transverse slidingmotion. A spring 24, mounted on a post 25, tends to hold the bolt in theretracted position. The bolt 23 is notched at 26 and 27 to aline withthe stump 15, according to which of two keys is inserted in the lock, asthe two keys may be cut differently and both used to open the lock. Onemay be used as a master key common to all of a series of locks, whilethe other may be used as an individual key. On the bolt is a pivot post28 on which the tumblers 30 are pivotally mounted. There is also on thebolt a projection 29 against which rest the tumbler springs 31;.. .[`he.lowersurface of. each tumbler is shaped so .alinement with the stumpaccording to the type of key used.

It will be seen by the above construction that while the stump isactuated by the key' so as to bring it in line with either the upper orthe lower set of notches in the tumblers and in the bolt, it is notcarried by the lever 18, but is merely actuated by it and can be madevery heavy and is rigidly supported by Vthe casing of the lock. rIhismakes an exceedingly substantial lock and one not liable to sufferinjury by the insertion of the wrong key therein. v While my inventionis particularly adapted to a padlock using a sliding bolt and tumblersand a stump, it may be used in connection with other types of lock wherethe same combination is found without departing from the essentialfeatures of the invention.

lVhile I have shown the tumblers and the sliding bolt each having twonotches, it will be understoo-d that the invention can be applied to alock in which the bolt and the tumblers may each have a single notch ormay have three or more notches, as desired, and, in so-me instances, thenotch or'notches may be only in the tumblers. By shifting the stump andchanging the location of the notches, numerous combinations can be made.

` I claim:

l. The combination in a lock, of a casing; a bolt and a tumbler, one ofsaid elements having a notch; with an independent sliding stump carrier;and a lever pivoted to the casing and arranged to actuate the slidingstump carrier and to be actuated by the key.

2. The combination in a lock, of a casing;

a notched bolt and notched tumblers carriedby the bolt; with anindependent stump carrier; and a lever pivoted .to the casing andarranged to actuate the stump carrier and to be actuated by theinsertion of the proper key into the lock.

3. The combination in a padlock, of a casing; a pivoted shackle; alocking dog arranged to engage the shackle; a bolt arranged transverselyin the casing; and a series of tumblers pivotally mounted on the bolt;said bolt and tumblers having notches; a stump carrier arranged to slideon the casing at the end of the bolt and tumblcrs, and arranged to bebrought into alinement with the notches above mentioned; with a leverpivoted to the casing and having a projection engaging the stump carrierand arranged to be actuated by the key of the lock.

4. The combination in a lock, of a casing; a bolt arranged to slidetransversely in the casing; tumblers carried by the bolt; the tumblersand bolt having notches at their ends; with an independent stump carrieradapted to slide at right angles to the movement of the bolt and againstthe casing and having a stump projecting toward the bolt and arranged toaline with the notches; with a spring-pressed lever pivoted to thecasing and having a projecting end located between the stump and the lugon the sliding stump carrier so that on the movement of the lever by thekey, the stump carrier will be shifted so as to be brought intoalinement with the notches.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
